U 290x80x2.66
BR — Cold-formed Channel
Cold-formed channels (U shapes) are similar to C shapes but without stiffening lips. Used for light structural framing, supports, and secondary members.
The U 290x80x2.66 steel profile weighs 13.8 kg/m (9.26 lb/ft), has a depth of 290 mm (11.42 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,175.8 mm². Moment of inertia Ix = 1,375.18 cm⁴, Iy = 60.55 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.66 mm ≈ 12 gauge (Manufacturers Standard Gage)
